Closed plastic support chain, full closed structure nylon chain closed plastic support chain (1) support chain shape of the tank chain, composed of numerous units to form a link chain link between rotating freely. (2) the same series of supporting chain of high, high, same pitch, inner width, bending radius R can have a different choice. (3) unit chain around the chain plate and the upper plate, a supporting chain of each section can be opened, convenient assembly and disassembly, without threading, open the cover to the cable, tubing, pipe, pipe into the towline. (4) a separate sheet can be provided, and the inner space of the supporting chain is separated according to needs. S support chain tank chain, S type engineering engineering towline towline towline universal S type tank chain, how to choose the suitable 1 Specifications: first you chain high: built-in cable, tubing, pipe, pipe etc. the most thick piece as the reference height at least plus 10% of the space height as the inner height. If the overlap is overlapped, the actual height is taken as the reference height. 2 width: some cable, the choice of coarse tubing, pipe, water pipe, the outer diameter of the supporting chain wide and as a reference, and the width of the space.3. has at least 10% if you have to drag chutes, in internal dimensions after combination note the towline wide, support chain wide is smaller than the width of the groove can be dragged for 3D towline, otherwise cannot move.4. if you are old machine replacement towline, please change the whole strip, if you only want to change the bad part of the cable towline, please choose the same brand chain, otherwise unable to dock, because each of the opening of the mold manufacturers are different.
